Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically a horizontal rotary table. Background Technology

[0002] A horizontal rotary table is one of the main components of a CNC machine tool, capable of rotating a workpiece to machine multiple surfaces. Currently, there are two main types of horizontal rotary tables: hydraulic rotary tables and servo rotary tables.

[0003] Existing equipment, such as CN210650196U, is a horizontal four-axis rotary table, including a mounting base, a drive mechanism, and a workpiece stage. The mounting base has a mounting surface, and the interior of the mounting base forms a mounting cavity. The mounting surface is parallel to the vertical direction. The workpiece stage is pivotally connected to the end of the mounting base away from the mounting surface via a rotating shaft. The drive mechanism is installed in the mounting cavity. The rotating shaft is parallel to the horizontal direction and extends into the mounting cavity, synchronously connected to the drive mechanism. The drive mechanism drives the rotating shaft to rotate. This utility model's horizontal four-axis rotary table allows the mounting base to be installed on a horizontal machine tool via the mounting surface of the mounting base, enabling the workpiece stage of the mounting base to rotate around the horizontal direction.

[0004] However, the existing horizontal rotary tables lack clamping and fixing devices, which cause them to move or shift due to vibration or other external forces during use, resulting in a decrease in machining accuracy. The existing horizontal rotary tables also lack protective buffer devices, which cause them to generate large vibrations and noises during use, thus affecting the surrounding people and environment. Therefore, the devices need to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a horizontal rotary table to solve the problems mentioned in the background art, such as the lack of clamping and fixing devices causing it to move or shift due to vibration or other external forces during use, resulting in a decrease in processing accuracy, and the lack of protective buffer devices causing it to generate large vibrations and noise during use, thus affecting the surrounding people and environment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a horizontal turntable, wherein a first fixed seat is movably connected to one side of a second fixed seat, a movable hole is provided on one side of the first fixed seat, and a clamping and fixing device is provided on one side of the second fixed seat. The clamping and fixing device includes a mounting frame, a lead screw is provided inside the mounting frame, a movable block is movably connected to the surface of the lead screw, and a connecting rod is fixedly connected to the surface of the movable block.

[0007] Furthermore, one side of the connecting rod is fixedly connected to the surface of the movable block, and the other side is fixedly connected to the surface of the first fixed seat. The movable block is threadedly connected to the surface of the lead screw, and a drive motor is provided on one side of the lead screw.

[0008] Furthermore, the first fixing seat has ten screw holes on its side, which are arranged in groups of five on both sides of the first fixing seat and the second fixing seat. Bolts are installed inside the screw holes.

[0009] Furthermore, a fixing block is fixedly connected to the top of the bolt, the first fixing block has an adsorption hole on its top, and the second fixing block has a heat dissipation hole on its top.

[0010] Furthermore, the first and second fixed seats are provided with protective buffer devices inside, the protective buffer devices including wear-resistant layers, the wear-resistant layers being fixedly connected to one side of the inside of the first fixed seat.

[0011] Furthermore, a reinforcing plate is fixedly connected to the surface of the wear-resistant layer, and the wear-resistant layer has two plates respectively distributed on one side inside the first fixing seat and the second fixing seat.

[0012] Furthermore, a return spring is fixedly connected to the surface of the reinforcing plate, and a protective layer is fixedly connected to the surface of the return spring. The equipment body is disposed between the two protective layers. Several return springs are distributed between the reinforcing plate and the protective layer. Several heat dissipation holes are respectively opened on the top of the second reinforcing base and penetrate the entire structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This horizontal rotary table, through the installation of a clamping and fixing device, utilizes a drive motor to rotate a lead screw. Simultaneously, the rotating screw moves a movable block and a connecting rod in front, causing the first fixed seat to move left and right to clamp the machine body. The fixed seat is then secured via screw holes and bolts through a fixing block, providing stable and reliable clamping to prevent workpiece movement or shaking during processing, thereby improving machining accuracy. The stable clamping and fixing device also shortens the time required for workpiece replacement and fixation, thus improving overall processing efficiency.

[0015] 2. This horizontal turntable, through a protective buffer device, utilizes a wear-resistant layer and reinforcing plate for initial protection, and then further protection and buffering through a return spring and protective layer. Adsorption holes and heat dissipation holes are used to dissipate heat internally, preventing overheating from affecting the equipment's lifespan. The buffer device can effectively absorb impact force when the workpiece or fixture collides with the turntable or other components, thereby reducing the risk of equipment damage and personnel injury. The buffer device can reduce downtime caused by equipment damage or malfunction, thereby improving production efficiency and the overall efficiency of the equipment. Attached Figure Description

[0025] Working principle:

[0026] By using a clamping and fixing device 4, the drive motor 403 drives the lead screw 402 to rotate. Simultaneously, the moving block 404 and the connecting rod 405 move, causing the first fixed seat 1 to move left and right, thus clamping the main body 8. The clamping device 4 then secures the workpiece to the fixing block 408 via screw holes 406 and bolts 407. This provides stable and reliable clamping, preventing workpiece movement or shaking during processing, thereby improving processing accuracy. The stable clamping and fixing device 4 also shortens the time required for workpiece replacement and fixation, thus improving overall performance. To improve processing efficiency, the protective buffer device 7 provides initial protection using the wear-resistant layer 701 and the reinforcing plate 702, followed by further protection and buffering using the return spring 703 and the protective layer 704. The device also utilizes the adsorption holes 5 and the heat dissipation holes 6 to dissipate heat internally, preventing overheating from affecting the equipment's lifespan. The buffer device effectively absorbs impact forces when workpieces or fixtures collide with the turntable or other components, thereby reducing the risk of equipment damage and personnel injury. It also reduces downtime caused by equipment damage or malfunction, thus improving production efficiency and the overall efficiency of the equipment.
